Subject: 	* config/arm/vfp.md (*push_multi_vfp): Use vfp_register_operand
X-Git-Tag: upstream/4.9.2~28161
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3cc80a304b23f16bc34c7479942d2865b01d61a6;p=platform%2Fupstream%2Flinaro-gcc.git

	* config/arm/vfp.md (*push_multi_vfp): Use vfp_register_operand
	as predicate for operand 1 and remove its constraint.
	* config/arm/predicates.md (vfp_register_operand): New.
	* config/arm/arm.md (*push_multi): Remove the constraint of
	operand 1.
	(*push_fp_multi): Likewise.
